Phantom 1.1.1 Gimbal problem - x1 port - pitch

Im trying to activate the pitch control on my ebay gimbal. I own a phantom 1.1.1 and when I conect it to the naza assistant, as I move the X1 controller in the back of the TX, nothing happens in the assistant software.
my question is, is the phantom 1.1.1 ready to operate a gimbal? do I need to replace the main controller for the V2? I cant get the X1 knob to work.

Pedro, are you sure the lever on the back of the transmitter is connecting with the little pot inside (does it feel like there's any resistance on it when you move it)? You may need to remove the lever and turn the pot manually with a screwdriver and see if you get any response in the Assistant software.

Also, is the Phantom powered on when you're testing that, and do you see response from the other control channels (sticks, switches)?
